| 摘 要： | 本文从盆地矿岩型铀矿产出层位，岩相及岩性序列组合特征，含矿砂体特征，铀矿化时代等方面总结了盆地砂岩型铀矿化的形成特征，提出了盆地卷状砂央型铀矿化是早期板状沉积一地预富集矿化基础上发展而来的成因观点。文中还对盆地铀矿化的空间展布规律进行了研究，指出了含矿性序列组合差异是导致盆地南缘东西矿化类型差异的原因，盆地后期抬升剥蚀程度差异是决定了主矿化层位高低差异的原因，并对盆地的找矿方向提出三条重要的参考意

| Abstract: | According to the occurrence layer, factes and lithological succession association characteristics, ore-bearing sand body characteristics, uranium mineralizatien age of sandstone type uranium deposit,this paper summarizes the formation characteristics of basin sandstone type uranium mineraligation and proposes the genetic view of basin convolution-like sondstone type uranium mineralization which develops from early plate-like sedimentary diagemesis mineralization preconcentration. The space distribution rule of basin uranium mineralization is studyed,and the reason of mineralization type difference between east and west in the south rim of basin is the difference of ore-bearing lithologl caf succession association. The high or low location of main mineralization layer depends on basin uplift and erosion level Three important proposals are suggested for prospecting ore orientation of basin. |
